The stock level effects low stock warning thresholds, as well as prevents out of stock items from being purchased.
Stock versus Stock Level
In Shopp 1.2, instead of a flat figure where low stock is indicated across all products, there is a low stock percentage, which will base low stock on the ratio of the current stock to the product’s stock stock level. For instance, if the the low stock threshold is 50% and the stock level is set to 20, low stock warning will appear when the product has less than 10 items.
// get the product priceline for product 2 $ProductPrice = shopp_product_variant( array('product' => 2), 'product'); // adjust the product stock to 10 without setting the stock level shopp_product_variant_set_stock ( $ProductPrice->id, 10, 'adjust', 'product' );
